This invention relates to a lighmd yo-yo;

It is an object of the present invention to provide a yo-yo which islighted and which will display two circles of light as the yo-yo body isworked on the string and wherein the light elements are turned on by acentrifugal switch which is moved in one direction when the yo-yo turnsin one direction and which is moved in another direction when the yo-yois turned in am other direction and wherein lights will appear from theopposite sides of the yo -yo.

Other objects of the resent invention are to provide a lighted yo-yo andswitch therefor which is of simple construction, inexpensive tomanufacture, has a minimum number of parts, of pleasing appearance,compact, durable, where the battery can be replaced by a simpleoperation, formed of transparent plastic to properly display the lightedbulbs and eflicient in operation.

For other objects and for a. better understanding of the invention,reference may be had to the followin detailed description taken inconnection with the accompanying drawing, in which Fig. l is aperspective View of the yo-yo in use and lighted to give the propereffect.

Fig. 2 is an enlarged vertical sectional View taken on line 2-2 of Fig.1.

Fig. 3 is a fragmentary, perspective and collective view of the body ofthe yo-yo with the covers removed and a display of the switch parts.

Fig. 4 is a wiring diagram of the light circuit.

Referring now to the figures, iii represents a central yo-yo body havinga deep groove i! in which yo-yo string i2 will operate. On the oppositefaces of this body it covers It and 14, having involute patterns arerespectively fitted. In the center of the body H3 is an opening throughwhich battery it extends to be supported.

Gn one side of the body it, there is fixed an enlargement ii to whichthere is fastened by a screw 18 a conductor strip I 9 that extends overthe central opening of the body and which is secured by a screw 2?; atthe opposite side of the opening. This strip 19 serves as a contact forone end of battery it.

On the enlargement ii and connected thereto by a pin 25 is a pivot arm22 which can be operatcd by centrifugal force. A spring 23 extendsbetween the arm 22 and pin 21 to normally hold the arm 22 in a The arm22 has an enlargement 24 at its outer end with side contacts thereon andwill move to have engagement with either contact projection 25 or 26 ofa contact plate 2'! having upstanding flange 28 on which the projections25 and 26 are centralized or neutral position.

formed. The plate 2? has a projection 3i engaging with a lamp bulb shell32 havin a filament 33 and held on the body by virtue of the springaction of the projection 3i acting upon the shell 32 and forcing thesame against an abutment 34. A contact 35 engages the contact end of thelamp bulb and extends across the surface of the body and downwardly, asindicated by the downwardly extending portion for engagement by a screw3'] on a projection or enlargement 38 on the opposite face of the yo-yo.The portion 36 of the contact 35 extends through the hole in the centerof the yo-yo.

Also connected by the screw 3? for pivotal displacement on theprojection 38 is a retaining arm contact 39 which engages with positiveterminal ii of the battery it and the outer end of which lies under anupstanding contact portion 32 of the contact strip lt secured to theopposite face of the body and which extends for engagement with the endof a lamp bulb 44 at that side of the yo-yo body. This lamp bulb 44 issimilarly held on that side of the body by engagement with an abutment,not shown, and which is held by a spring contact projection 45 thatextends from contact plate 2i and through the hole in the center of thebody.

The arm 22 will be operated by centrifugal force and will move firstagainst projection 26 when the yc-yo is rotated in one direction andthen against projection 25 when the yo-yo is rotated in the oppositedirection.

It will be seen that the battery is fixedly retained within the body andconsumes little space. By a mere removal of the contact arm 39 from theportion 42 of the contact strip 43, the battery can be lifted from theopening in the body. When the yo-yo is out of use and lying flat, thespring 23 will centralize the arm so that there is no contact witheither projection 25 or 25, Fig. 2, and thus automatically the lampbulbs will be put out of use. Centrifugal action will only operate thearm 22.

It will be seen from the circuit shown in Fig. 4 that the lamp bulbs arein parallel circuit relation with each other and with the battery 16 andthe weighted switch arm 22 engagable with either of the contacts 25 or26 of the contact strip 21. The weighted arm 22 will engage contact 25as the yo-yo rotates in one direction and with the other contact it willbe engaged when the yo-yo rotates in the opposite direction. Beginningwith the battery l6 current passes through contacts or pivotal retainingmember 39, contact strip 43, lamp bulb 44, lamp bulb 33 through contactstrip 3 35, contact member 27 engaging both lamp bulbs 33 and 44,contact 25 or 25, Weighted arm 22, contact strip I9 and back to batteryi6.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claims.

What is claimed is:

1. A lighted yo-yo construction comprising a main body having a deepgroove, a yc-yo string extending from the groove, said yo-yo body havinga central opening, a battery extending through the central opening, acontact strip extending over the central opening on one side of theyo-yo body and serving as a contact for the battery, a retaining contactmember pivotally connected to the opposite side of the yo-yo body andengaging with the opposite end of the battery, a fastener contact forreceiving the retaining contact member, lamp bulb means carried on theyo-yo body, a contact member on the yo-yo body in circuit with the lampbulb means and battery and having two contact projections, a weightedswingable contact arm spring biased to a neutral position and adapted toengage either one of the two contact projections upon the yo-yo beingoperated, but adapted to be centralized when the yo-yo is out ofoperation whereby to de-energize the lamp circuit.

2. A lighted yo-yo structure comprising a yo-yo body having a deepgroove therein, a yo-yo string extending from the groove, said yo-yobody having a central opening, a battery extending through the centralopening, a contact strip extending over the opening at one side of the0-3 0 body, a switch arm pivotally connected to the contact strip, saidswitch arm being weighted and adapted to be operated by centrifugalaction, biasing means for normally holding said weighted switch arm in aneutral position when the yo-yo is not in use, a contact member havingtwo circumferentially-spaced contact projections extending from the sameand adapted to be engaged by the weighted switch arm depending upon thedirection in which the yo-yo body is rotated, said contact member havingother projections thereon one of which extends through the opening inthe yo-yo body, the ends of said projections being bent up torespectively provide holding contacts, lamp bulbs respectively disposedunder the respective holding contacts of the ends of the projections ofthe contact member, abutment means on the yo-yo body associated witheach of the lamp bulbs for retaining the lamp bulbs, a second contactstrip extending from one terminal of one lamp bulb through the openingin the body and lying on the other side of the body, a retaining contactmember pivotally connected to said second contact strip and engageablewith a terminal of the battery, another contact strip engageable withthe retaining contact member and leading into engagement with a terminalof the other lamp bulb.
